• Visual Basic Problem with Tab Groups in VS2005, programing in C#

  I have run into two problems when using tab groups in the VS editor. 1. If I have two tab groups organized vertially (never tried hz.) after navigating in a file in the second group, after clicking to edit a file in the first group I can not make any edits. I can use the arrow keys, and I can actually delete text, but I can not enter any new text. Simpy clicking on a different file in that tab group, then clicking back to the original file solves the problem. It acts like the first tab group does not get proper focus when comming from the second group, however some of the keys work. 2. If I close VS2005 when I have two tab groups open, the project will not open properly the next time. VS comes partialy up but hangs with a totally whi ...Show All

• Windows Forms Cannot download the application error!

  Not sure how this happened, but I am no longer able to run my application that I have published. I originally had about 95 revisions published and started getting this error. I manually deleted all the builds from the publish directory, removed my application from the add/remove program, deleted all related file folders under Local Setting/App/2.0, ran mage -cc, etc... I have tried all of that and I still cannot get my application to deploy and run anymore. It seems like the deploymentUrl should be where I am publishing to but my manifest seems to indicate that it is looking at my local drive. Help! I need to get this working again. I am on the verge of rebuilding the project. PLATFORM VERSION INFO Windows : 5.1.2600.131072 (Win3 ...Show All

• SQL Server Key Maintenance and Stored Procedures

  Basically I would like to ask whether parameters can be used to pass the value of the 'symmetric key id', 'certificate' and optionally 'password' to a stored procedure that uses encryption functions. The reason this is appealing is that when encryption keys etc change over time (we have a requirement to decrypt data, destroy and create new keys, then encrypt data every time we lose a staff - don't ask), as we would be passing the value of keys, passwords and certificates as parameters to a standard stored procedure. Hardcoded Example (Working) USE PSS GO CREATE PROC insert_payer_ba -- define parameters @param_rec_id NVARCHAR ( MAX ), @param_bsb NVARCHAR ( MAX ), @param_account NVARCHAR ( MAX ), ...Show All
